A photosensitive composition comprising, (A) an oligomer or polymer containing at least one carboxylic acid group in the molecule and having a molecular weight of 200'ooo or less; (B) at least one photoinitiator compound of formula I, R1, is lenear or banched C1-C12alkyl; R2 is linear or branched C1-C4alkyl; R3 and R4 independently of one another are linear or branched C1-C8alkyl; and (C) a monomeric, oligoneric or polymeric compound having at least one olefinic double bond, is especially suitable for preparting photoresists, in particular color filters.
